PURPOSE:To change a set current value of the criterion of determination of overcurrent in a short time easily from a remote place by providing a data receiving means which can receive set current value change data transmitted from a control station and a set current value changeover circuit which changes over the set current value on the basis of the set current value change data. CONSTITUTION:The title current limiter A has an overcurrent detecting circuit 3 and a breaking control circuit 4 which outputs a breaking control signal S3. On the other hand, the current limiter A is provided with a transmission control element 5, which is connected to a transmission control element in a control station B through a communication circuit C. The transmission control element 5 can receive set current value change data transmitted from the control station B, and it checks up the received data and processes them properly and then outputs a selection signal S4 for changing over a changeover switch 6a of a set current value changeover circuit 6 on the basis of the received data. |
